STATES PATENT 2 Claims.

The purpose of my improvement is to provide a light portable devicesuitable for painting ceilings and walls of buildings, which devicecon-.

tains both means to apply paint and a supply of paint for that purpose.

Another object of my invention is to provide a device of simpleconstruction and a few parts, in such a combination that they do not geteasily out of order.

A further object of my improvement is to provide a machine includingmeans for control of its operation, particularly with respect to meansof applying paint to the surface to be painted.

I shall now describe my invention with reference to the accompanyingdrawings, in which:

Fig. 1 is a perspective view of the whole machine, with some parts beingshown in less than full relative length.

Fig. 2 is a diagrammatic view of the machine with respect to the surfaceto be painted with the aid 'of' said machine.

Fig, 3 is an end view of the upper part of the machine shown in Fig.1,inc1uding a tank for paint, with an end wall thereof removed to showparts within.

Fig. 4 is a perspective view of a drum, being a part of my machine.

Fig. 5 is a side elevation of a detail of my machine.

. Fig. 6 is a front elevation of the upper part of my machine, thisbeing the side 'to face the wall to be painted.

Fig. '7 is the top view of a tank, which is a part of my machine.

Similar numerals refer to similar parts throughout the several views.

The machine consists generally of a tank It, designed as a receptaclefor liquid paint, a roller ii mounted above the tank, and an elongatedshank 92. Tank i0 is cylindrical in shape and open at one end, for whichend a removable cap i l provides a closure. Normally, the tank isdisposed in a horizontal position. Its cylindrical wall is open at whatis. normally its upper side. The opening i3 is substantiallyrectangular, as shown in Fig. '7, and extends substantially the wholelength of the tank. Axially disposed within the tank is a drum 14. Thelatter is mounted for rotation around its axis in a spider. I5, which ismade of a band of metal or suitable material. The band runs along thesurface of drum I l, as shown by numeral l6, turning up at both ends toprovide bearing ii for axle it of the drum and spreads apart into aV-formation I8, each leg. of said v-formation being bent. inwardly overthe surface of drum It, the bent over portions forming short extensionsi9. These serve as anchorage points for elastic skimmers 20, preferablymade of rubber. The skimmers are in close proximity to the surface ofdrum It. The radial distance of extensions 59 and member I 6 from axle46 are such that said extensions and the band fit closely against theinside surface of tank It) and are in a frictional contact with saidsurface. Said extensions is are intended to straddle the longer sides ofopening it, as-

shown in Fig. 3.

Mounted above opening E3 in tank 10 is a roller The roller is hollow,its outer surface being covered with a textile material of the kind usedfor conventional rollers employed for painting walls, and includes anaxle protruding at each end. At one end, the protruding part of the axlefits into a slot 23 in a bracket 2! extending radially from the end wallof tank l0. At the other end, bracket 22 rises from the upper surface oftank in adjoining opening i3. With the ends of its axle in slots ofrespective brackets, roller H is mounted right above said opening l3,which is somewhat longer than said roller H, said roller abuttingfrictionally the surface of drum it within tank iii.

The machine includes means whereby the contact between the drum withintank 10 and the roller I iv may be discontinued should it be so desired.The means are controlled by a trigger adjacent handle 25. Said meansinclude a lever made of one continuous length of wire. The wire is madeinto a loop 30 at one end of the roller so as to enclose the end of axle2t, turns parallel to the axis of said roller running within bead iii,to a point mid-way the length of tank ill, extends at right angle tosaid axis in a curve 32 approximately following the outline of tank l0,makes a hairpin turn 33 and returns upwardly to form a symmetricalcounterpart, terminating in a loop to enclose the other end of saidaxle. The lever so made is fulcrumed in said beads 3| on both sides ofshield 65, arching over the wire where it starts on its downward curve32.

The tank it is held in a cradle composed of semi-circular bands 25. Thebands are heldhi a spaced relation by prongs 28 of shank it, made of twoparallel wires 25, anchored to handle 25. A trigger 36 held between theends of band 21 by means of pin All and including a finger-piece M, isconnected to a rod 35 running between wires 26, and forms at its outerend an eye 36. The latter encloses the hairpin turn 33 of the leverfulcrumed in. beads ti. A Spring 31 coiled around said rod 35 is at oneend afflxed to the rod. At the opposite end, it bears against acrossmember 8!, binding together said shank wires 26. The cross-membercontains an aperture 39 for sliding passage of said rod 35. A screw 42in an upright lug 48 on handle 28, is used to regulate the extent of themovement of trigger 38.

I shall now describe the manner in which my machine may be used; First,cap 44 is put into its place and a quantity of liquid, paint is pouredinto said tank through opening i3. To gain access to said opening, theroller I! must be shifted upwardly, away from contact with drum itwithin the tank. This shifting may be done manually or indirectly bymeans of trigger 88, as will be hereinafter described. With the tankproperly filled with paint, the machine is held in an upright positionat an angle to bring the roller ll into contact with the wall to bepainted. As the machine is pushed upwardly, or pulled downwardly, theroller, being in frictional contact with the wall, is made to rotate.Because the roller is also in a frictional engagement with the drum, therotation of the roller causes the rotation of the drum. As the latter isimmersed in liquid paint, it gathers, in the course of its rotation, aquantity of paint on its surface and brings it upwardly to feed saidroller II. Excess quantity of paint is brushed off by skimmers 20. Theremaining quantity of paint is picked up by the surface of roller II andis applied to the surface which is to be painted.

, If in the course of the operation it is desired to app y the roller tothe surface to be painted, but to discontinue the contact of the rollerwith the paint supplying drum, this may be eflected by the action of thetrigger it. As the trigger is pulled by means of finger-piece 4!, eye 34of rod 35 pushes down-the lower end of the lever which controls positionof roller II, and causes loops 3! to rise upwardly and to remove saidroller II from contact with drum M. This is shown in Fig. 3, where theposition of roller H away from aasaeoa drum I4 is shown in dotted linesHa. when the finger-piece 4| is released, the roller, under the actionof coiled spring 31, returns automatically to its normal position. thatis, into contact with said drum M.

It is obvious that some changes may be made in the construction of mymachine without departing from the inventive principle disclosed herein.What I, therefore, wish to claim is as follows:

1. A machine of the kind described, comprising a cylindrical tank forliquid paint, the tank being open at upper side, a bracket mounted onthe tank at each end thereof, and extending radially therefrom, eachbracket being provided with a slot therein, radially disposed withrespect to said tank, a roller for application of paint to the surfaceto be painted, said roller being disposed over said opening and beingmounted for rotation in said brackets by means of its axle, extending ateach end into the respective slot, a drum axially disposed within thetank and being in a frictional contact with the surface of the roller tobe rotated by the rotation thereof, a handle to support the tank, andlever means extending from said handle to the axle ends of the roller todiscontinue the frictional contact between the roller and the drum.

2. A machine of the kind described, comprising a tank for liquid paint,the tank beingopen at its upper side, a roller mounted horizontally oversaid opening on its axle ends in brackets having downwardly extendingslots therein, a paint supplying drum mounted for rotation within thetank, parallel to the roller and in frictional contact with its surface,to be rotated thereby, lever means applicable to the roller to lift saidroller above the drum, to discontinue frictional contact therewith, andmeans to support the tank with the roller thereon for operation.

JOHN BRZESKI.
